### MOTION AND TIME :

MOTION AND TIME Motion – The change in the position of a body with time is known as Motion. Types of motion:- Translatory motion Rotatory motion Rolling motion Periodic motion Oscillatory and Vibratory motion

### Translatory motion :

Translatory motion The motion in which a body moves as a whole and every point on it moves the same distance is called translatory motion. There are three kinds of translatory motions:- Linear motion Curvilinear/Circular motion Random motion

### Linear motion :

Linear motion The movement of a body along a straight line is called linear motion. For e.g.: A car moving in a straight line.

### Example of Linear motion :

Example of Linear motion

### Curvilinear motion :

Curvilinear motion The movement of a body along a curved path is called curvilinear motion. Curvilinear motion is also known as circular motion. For e.g.: motion of a car along a curved path.

### Example of Curvilinear motion :

Example of Curvilinear motion

### Random motion :

Random motion The translatory motion of a body which keeps on changing its direction in a disorderly manner is called random motion. For e.g.: motion of a Football when kicked (for some time).

### Example of random motion :

Example of random motion

### Rotatory motion :

Rotatory motion The motion of a body in which every particle on it moves along a circular motion about a fixed axis is called rotatory motion. For e.g.: A spinning top.

### Example of Rotatory motion :

Example of Rotatory motion

### Rolling motion :

Rolling motion The motion in which a body undergoes both translatory as well as rotatory motions is known as rolling motion. For e.g.: A cylindrical object rolling from a slope surface.

### Example of rolling motion :

Example of rolling motion

### Periodic motion :

Periodic motion The motion which repeats itself at a regular interval of time is known as periodic motion. For e.g.: Motion of the Earth around the Sun.

### Example of periodic motion :

Example of periodic motion

### Oscillatory And Vibratory motion :

Oscillatory And Vibratory motion The to-and-fro motion of a body along the same path is known as oscillatory motion. For e.g.: Motion of a pendulum. Small and rapid to-and-fro movement of a body or a part of it from its mean position is called vibratory motion. For e.g.: Movement of string of a guitar.

### Example of oscillatory motion :

### Example of vibratory motion :
